Here's a code challenge I got. (I could not solve the challenge, I ran out of time. I rephrased the challenge language and I am trying the challenge again for personal growth & computer science knowledge)

Consider an array A of N integers. You can delete zero or more of its elements.

Then take the remaining elements and reduce to an integer S according to these rules:

  • elements in even positions are added
  • elements in odd positions are subtracted: e.g. S = A[0] − A[1] + A[2] − A[3] + ...

Code Challenges
Write a function solution that, given a string S consisting of N letters 'a' and/or 'b' returns true when all occurrences of letter 'a' are before all occurrences of letter 'b' and returns false otherwise.
1. Given S = "aabbb", the function should return true.
2. Given S = "ba", the function should return false.
3. Given S = "aaa", the function should return true. Note that 'b' does not need to occur in S.
